It is 1943. Sergeant Wyatt Corwin and his elite squad of enhanced super soldiers have gone back in time in pursuit of the most dangerous man in history, the genius Maximilian Villiers. They must stop him from changing the world forever. But the war has not progressed as Corwin's history books taught it.

The world is on the brink of falling to the Nazis. Villiers is pulling the strings to advance Nazi technology beyond their wildest dreams. Heavily armored personnel suits, squadrons of jet fighters, and advanced bipedal walkers are turning the tide of the war. But few believe in the existence of this new puppet master. Corwin is tasked with a near impossible mission, to kill the man who presents the biggest threat to world peace. This man is the Fuehrer himself, Adolf Hitler. Now a captain among the allies, Corwin and his team must embark on a deadly mission deep within enemy territory, alone, and with no means of escape. They must track down and kill Hitler, or die trying.

Onslaught is the second installment in the epic new Time War series that throws futuristic super soldiers into an alternate history. They must fight the ultimate enemy in a world that is entirely alien to them where the security of the free world and the future of humanity is at stake.
